[PATCH 1/2] ath11k: Fix memory leak on error path

[Alex Dewar]

In ath11k_mac_setup_iface_combinations(), if memory cannot be assigned
for the variable limits, then the memory assigned to combinations will
be leaked. Fix this.

Addresses-Coverity-ID: 1497534 ("Resource leaks")
Fixes: 2626c269702e ("ath11k: add interface_modes to hw_params")
